Simply add up the weight on the barbell by tapping the corresponding weight plates and see the total at the bottom.
Once you can put up weight worth bragging about, tap the "Tell A Bro" button to text a friend the current weight you just lifted.
Backstory:
I grew up as a child seemingly normal, just like all the other kids at my school. That was, until I quickly started maturing. Day by day, my muscles were morphing and becoming more and more visible and developed. Playing games like tag on the playground with the other kids was no longer fun. I was too fast and too strong for childish play. I was banned from playing kickball, for I kicked the ball out of the school property too many times. The principal eventually forbid me to have recess with the other kids... instead I was required to report to the gym teacher and he gave me things to do. He wanted to exploit my unique ability of strength by having me lift weights. Before I knew it, I was setting records... benching, squatting, hang cleaning, crossfitting more weight than body building legends. There came a point when humans could no longer easily add up the weight I had on the barbell. Thus Plate Weight birthed.. an app that would allow scientists, trainers, and fans to add up the quickly weight I was lifting. I chose to make the app public in hopes that one day, maybe you too will have a need for such an app.
Good luck
